Acceleration - Angular Conversion

Angular acceleration is the rate of change of angular velocity. In SI units, it is measured in radians per second squared (rad/s2 or rad⋅s−2), and is usually denoted by the Greek letter alpha (α). Angular acceleration is a vector quantity which indicates the speed of rotation of an object about an axis. It is commonly used in sports (such as gymnastics, figure skating, and diving), data storage on optical media (such as CD).
